<h1>Creating Core System Classes<a class="headerlink" href="#creating-core-system-classes" title="Permalink to this headline">¶</a></h1>
<p>Every time CodeIgniter runs there are several base classes that are initialized automatically as part of the core
framework. It is possible, however, to swap any of the core system classes with your own version or even just extend
the core versions.</p>
<p><strong>Most users will never have any need to do this, but the option to replace or extend them does exist for those
who would like to significantly alter the CodeIgniter core.</strong></p>

<h2>Replacing Core Classes<a class="headerlink" href="#replacing-core-classes" title="Permalink to this headline">¶</a></h2>
<p>To use one of your own system classes instead of a default one, ensure that the <a class="reference internal" href="../concepts/autoloader.html"><span class="doc">Autoloader</span></a>
can find your class, that your new class extends the appropriate interface, and modify the appropriate
<a class="reference internal" href="../concepts/services.html"><span class="doc">Service</span></a> to load your class in place of the core class.</p>
<p>For example, if you have a new <code class="docutils literal notranslate"><span class="pre">App\Libraries\RouteCollection</span></code> class that you would like to use in place of
the core system class, you would create your class like this:</p>
<div class="highlight-html+php notranslate"><div class="highlight"><pre><span></span><span class="o">&lt;?</span><span class="nx">php</span>

<span class="k">namespace</span> <span class="nx">App\Libraries</span><span class="p">;</span>

<span class="k">use</span> <span class="nx">CodeIgniter\Router\RouteCollectionInterface</span><span class="p">;</span>

<span class="k">class</span> <span class="nc">RouteCollection</span> <span class="k">implements</span> <span class="nx">RouteCollectionInterface</span>
<span class="p">{</span>
    <span class="c1">// ...</span>
<span class="p">}</span>
</pre></div>
</div>
<p>Then  you would modify the <code class="docutils literal notranslate"><span class="pre">routes</span></code> service to load your class instead:</p>
<div class="highlight-html+php notranslate"><div class="highlight"><pre><span></span><span class="k">public</span> <span class="k">static</span> <span class="k">function</span> <span class="nf">routes</span><span class="p">(</span><span class="nx">bool</span> <span class="nv">$getShared</span> <span class="o">=</span> <span class="k">true</span><span class="p">)</span>
<span class="p">{</span>
        <span class="k">if</span> <span class="p">(</span><span class="nv">$getShared</span><span class="p">)</span>
        <span class="p">{</span>

<h2>Extending Core Classes<a class="headerlink" href="#extending-core-classes" title="Permalink to this headline">¶</a></h2>
<p>If all you need to is add some functionality to an existing library - perhaps add a method or two - then it’s overkill
to recreate the entire library. In this case, it’s better to simply extend the class. Extending the class is nearly
identical to replacing a class with one exception:</p>
<ul class="simple">
<li>The class declaration must extend the parent class.</li>
</ul>
<p>For example, to extend the native RouteCollection class, you would declare your class with:</p>
<div class="highlight-html+php notranslate"><div class="highlight"><pre><span></span><span class="o">&lt;?</span><span class="nx">php</span>

<span class="k">namespace</span> <span class="nx">App\Libraries</span><span class="p">;</span>

<span class="k">use</span> <span class="nx">CodeIgniter\Router\RouteCollection</span><span class="p">;</span>

<span class="k">class</span> <span class="nc">RouteCollection</span> <span class="k">extends</span> <span class="nx">RouteCollection</span>
<span class="p">{</span>
    <span class="c1">// ...</span>
<span class="p">}</span>
</pre></div>
</div>
<p>If you need to use a constructor in your class make sure you extend the parent constructor:</p>
<div class="highlight-html+php notranslate"><div class="highlight"><pre><span></span><span class="o">&lt;?</span><span class="nx">php</span>

<span class="k">namespace</span> <span class="nx">App\Libraries</span><span class="p">;</span>

<span class="k">use</span> <span class="nx">CodeIgniter\Router\RouteCollection</span> <span class="k">as</span> <span class="nx">BaseRouteCollection</span><span class="p">;</span>

<span class="k">class</span> <span class="nc">RouteCollection</span> <span class="k">extends</span> <span class="nx">BaseRouteCollection</span>
<span class="p">{</span>
    <span class="k">public</span> <span class="k">function</span> <span class="fm">__construct</span><span class="p">()</span>
    <span class="p">{</span>
        <span class="k">parent</span><span class="o">::</span><span class="na">__construct</span><span class="p">();</span>
    <span class="p">}</span>
<span class="p">}</span>
</pre></div>
</div>
<p><strong>Tip:</strong>  Any functions in your class that are named identically to the methods in the parent class will be used
instead of the native ones (this is known as “method overriding”). This allows you to substantially alter the CodeIgniter core.</p>
